those on the sides and flanks, margined with brownish buff; 

 a few pale scarlet feathers indicate the colours of the adult, 

 but are much less brilliant. 



In more advanced examples the upper parts entirely 

 resemble those of the fully adult bird, but the slate-blue on 

 the wings is almost wanting; the fore-neck and chest are 

 still intermixed wdth white-and-buff-centred feathers, and on 

 the rest of the underparts the scarlet feathers of the adult 

 and the whitish buff of the juvenile plumage are represented 

 in about equal parts. 



It is difficult to imagine anything more glorious than the 

 colours of the fully adult male, the brilliant scarlet of the 

 lower breast and belly contrasting vividly with the shining 

 slate-blue chest. 



The adult female differs from the male only in having the 

 colours of the underparts rather less brilliant.

A female example of the Tufted Tree-Swift was obtained

75. CoLLOCALIA WHITEHEADI, Sp. n. 



Mr. Whitehead has forwarded four examples of this new 

 species, which I at first sight referred to Low's Swiftlet 

 (C. lowi), though with considerable hesitation, for it appeared 

 to me that among the birds referred to this species by Mr. 

 Hartert [Cat. B. Brit. Mus. xvi. p. 498 (1892)] there were 

 examples of at least two, if not three species, judging from 

 the length of the wing, shape of the tail, and feathering of the 

 tarsi. In the four birds from the Lepanto district the wing- 

 measurements vary from 5'2 to 5*5 inches; all have the tail 

 distinctly forked, the middle pair of feathers being a quarter 

 of an inch shorter than the outer pair; also the tarsi entirely 

 naked. A female from Palawan, recently obtained from 

 Mr. Everett (wing 5-15 inches), is perfectly similar in all 

 respects to the Lepanto birds, having the freshly-moulted 

 tail very distinctly forked and the tarsi devoid of anv trace of
